Title: Hydrofining catalyst and hydrofining process
Inventor: KUMAGAI HIDEAKI
IPC: C10G65/04
Filed: 2001-06-07
Granted: 2011-04-05
Abstract: A heavy oil hydrorefining catalyst of the present invention is such that the total volume of pores with a diameter of 60 nm or less is at least 0.5 mL/g, and the pore diameter distribution has a broad band over a pore diameter range of 8 to 30 nm. The hydrorefining catalyst has excellent desulfurization characteristics and excellent demetalization characteristics, and its performance can be maintained over an extended period. When this catalyst is used in a hydrorefining apparatus equipped with a plurality of catalyst layers, the apparatus can be operated stably at a higher temperature than in the past without decreasing the desulfurization performance, and this also enhances the demetalization characteristics.

Abstract: The lifetime of a double-cone device (21) for creating a pressure difference in a streaming fluid can be greatly increased by moving the inlet gap (5) in to the exit cone (4). This results in a short so-called diffuser (22) being obtained between the gap (5) and the orifice (19), where entry cone (3) and exit cone (4) are connected. The increased lifetime permits the double-cone device to cope with much higher flow rates. Thus higher system pressures are created which enhance the use of the double-cone for such applications as th e desalination of sea water by reverse osmosis. The important application of t he separation of oil from water using a separating device such as a cyclone (57 ) working under elevated pressure is now feasible. The increased power of the double-cone permits one to profit more fully from the new concept of reducti on of the concentration of the feed supplied to the double-cone device (21).</S DOAB>

Title: Fuel cell stack with recycling
Inventor: STOLTEN DETLEF
IPC: H01M8/04186
Filed: 2001-11-06
Granted: 2010-02-09
Abstract: In a direct-methanol fuel cell stack with an at least partial circulation (7, 9) of the fuel, according to the invention a means is arranged in this circulation for reducing the concentration of an undesired byproduct. This means is comprised especially of a further electrochemical cell (8) to which electric current is applied and which at least partly transforms the byproducts by an electrochemical reduction reaction again to methanol and water. Since the concentration of byproducts is small, the loss in electric current required for the additional reduction reaction has no noticeable effect on the efficiency of the fuel cell stack.

Title: Controller of internal combustion engine
Inventor: WATANABE SATORU
IPC: F02D13/02
Filed: 2001-12-12
Granted: 2007-05-15
Abstract: A device for controlling an internal combustion engine, comprising a variable valve mechanism for varying opening areas (valve lift) or the working angles (valve--opening periods) of at least either the intake valves or the exhaust valves, wherein a pressure in the cylinder is calculated based on the opening area or the working angle of at least either the intake valve or the exhaust valve varied by the variable valve mechanism, and the internal combustion engine is controlled based on the pressure in the cylinder. Upon calculating the pressure in the cylinder based on the opening areas or the working angles of the intake and exhaust valves, it is possible to more suitably control the internal combustion engine based not only upon the peak combustion pressure in the cylinder like when a combustion pressure sensor is used but also upon a pressure in the cylinder at a moment other than the peak combustion pressure.

Granted: 2012-05-01
Abstract: Disclosed are methods for determining the stage of neurofibrillary degeneration associated with a tauopathy in a subject believed to suffer from the disease, which methods comprise the steps of: (i) introducing into the subject a ligand capable of labelling aggregated paired helical filament (PHF) tau protein, (ii) determining the presence and/or amount of ligand bound to extracellular aggregated PHF tau in the medial temporal lobe of the brain of the subject, (iii) correlating the result of the determination made in (ii) with the extent of neurofibrillary degeneration in the subject. The methods can be used for pre-mortem diagnosis and staging of tauopathies such as Alzheimer's Disease. Preferred ligands include sulphonated-benzothiazole-like compounds and diaminophenothiazines. Novel ligands (e.g. sulphonated-benzothiazole-like compounds) are also provided. The method may also include the use of "blocking ligands" to block competing binding sites. In other aspects the invention provides in vitro methods for identifying ligands capable of labeling aggregated PHF tau protein, the methods comprising the steps of: (i) providing a first agent suspected of being capable of labeling aggregated PHF tau protein, (ii) contacting (a) a tau protein or a derivative thereof containing the tau core fragment bound to a solid phase so as to expose a high affinity tau capture site, with (b) a liquid phase tau protein or derivative thereof capable of binding to the solid phase tau protein or derivative, and (c) said selected first agent and (d) a second agent known to be tau-tau binding inhibitor, (iii) selecting first agent which fully or partially relieves the inhibition of binding of the liquid phase tau protein or derivative of (b) to the solid phase tau protein or derivative of (a) by the inhibitor (d). Ligands may also be tested to confirm that they are not themselves inhibitors.

Abstract: The use of low specific gravity wood from thinning operations, for example, will produce a lower brownstock viscosity for a given kappa number target. A differential of 200-cP falling ball pulp viscosity has been detected from Kraft cooks of low and high specific gravity wood. Using low specific gravity wood can reduce the bleach stage temperature and the chemical dose needed in the bleach plant to produce lyocell pulp specifications. Low specific gravity wood also increases the ability to reduce pulp viscosity to very low levels without increasing the copper number of the pulp or the concentration of carbonyl in the pulp above acceptable levels.
